Description
Vidrios alcalinos con superficies modificadas y procedimiento para su producción.Alkaline glasses with modified surfaces and Procedure for its production.
En el uso de los vidrios, las propiedades superficiales de éstos en relación con la interacción con el entorno desempeñan un papel esencial, debiendo mencionarse en este contexto en particular las propiedades químicas y mecánicas. Por diferentes motivos, relacionados entre otras cosas con la fusibilidad y la tecnología de fusión, frecuentemente son deseables unos contenidos de álcali relativamente altos, pero éstos conducen por otro lado a una reducción de la resistencia hidrolítica y las propiedades mecánicas. Una solución usual hasta la fecha a este dilema consiste en un tratamiento superficial definido en general mediante procesos de desalcalinización, tal como se presentan resumidos en [1: Glastechnische Fabrikationsfehler, H. J. Jebsen-Marwedel, R. Brückner: Editorial Springer 1980, páginas 507508] y en [2: Solicitud de Patente Oficina Alemana de Patentes y Marcas. Verfahren zur Herstellung von Emails, referencia 102 46 928.8]. En esta problemática de la desalcalinización, por ejemplo mediante influencia de vapor de agua sulfúrea, etc., surge un problema fundamental consistente en que para lograr una alta reactividad generalmente se requieren altas temperaturas de reacción, pero éstas pueden conducir a su vez a una retrodifusión de sodio del volumen en la superficie. Sobre todo en caso de procesos de tratamiento posteriores, como un procesamiento posterior bajo llama, que implica altas temperaturas, la retrodifusión de sodio del volumen provocada térmicamente puede conducir a una degradación significativa de las propiedades logradas en un principio.In the use of glasses, the properties superficial of these in relation to the interaction with the environment they play an essential role, and should be mentioned in this context in particular the chemical and mechanical properties. For different reasons, inter alia related to fusibility and fusion technology, contents are often desirable of relatively high alkali, but these lead on the other hand to a reduction in hydrolytic resistance and properties mechanical A usual solution to date to this dilemma is in a surface treatment defined in general by processes of desalkalization, as presented in [1: Glastechnische Fabrikationsfehler, H. J. Jebsen-Marwedel, R. Brückner: Springer Editorial 1980, pages 507508] and in [2: German Office Patent Application of Patents and Trademarks. Verfahren zur Herstellung von Emails, reference 102 46 928.8]. In this problem of desalkalization, for example by influence of water vapor sulfur, etc., a fundamental problem arises in that to achieve high reactivity, high levels are usually required reaction temperatures, but these can in turn lead to a sodium backscatter of surface volume. Specially in case of subsequent treatment processes, such as processing later under flame, which implies high temperatures, the sodium backscattering of the thermally caused volume can lead to a significant degradation of the properties achieved initially.
El documento US5510144 describe un método para impedir la retrodifusión de iones de plomo hacia la superficie de vidrio mediante tratamiento con vapores de sulfato de aluminio y hierro. El documento JP60176952 da a conocer un tratamiento superficial de vidrio para evitar la corrosión atmosférica con soluciones ácidas de sulfato de aluminio a 20-90ºC, que opcionalmente también pueden contener cloruro de aluminio.US5510144 describes a method for prevent back-diffusion of lead ions towards the surface of glass by treatment with aluminum sulfate vapors and iron. JP60176952 discloses a treatment surface glass to prevent atmospheric corrosion with acidic solutions of aluminum sulfate at 20-90 ° C, which may also optionally contain aluminum chloride.
El objetivo técnico de la invención consiste en estabilizar la superficie de vidrio modificada de tal modo que, a diferencia del estado actual de la técnica, se evite en gran medida una retrodifusión de sodio del volumen también a altas temperaturas, y en particular en caso de procesamientos posteriores con llama.The technical objective of the invention consists in stabilize the modified glass surface such that, at Unlike the current state of the art, it is largely avoided a sodium backscatter of the volume also at high temperatures, and in particular in case of subsequent processing with flame.
Sorprendentemente se comprobó que una superficie modificada de un vidrio alcalino es muy resistente a una retrodifusión de sodio del volumen a altas temperaturas si el mecanismo químico dentro de la superficie presenta una concentración de aluminio claramente mayor que la del volumen. La causa puede radicar en la altísima entalpia de formación negativa de fases de albita. El procedimiento según la invención se caracteriza porque la superficie de estos vidrios se pone en contacto con compuestos de cloruro de aluminio en fase de vapor.Surprisingly it was found that a surface modified from an alkaline glass is very resistant to a sodium backscattering of the volume at high temperatures if the chemical mechanism within the surface has a concentration Aluminum clearly larger than the volume. The cause can lay in the very high enthalpy of negative phase formation of albite. The method according to the invention is characterized in that the surface of these glasses is contacted with compounds of aluminum chloride in vapor phase.
Se pueden evitar perjuicios ópticos si el material aluminifero de la fase gaseosa se condensa en superficie de vidrio y al mismo tiempo pasa a formar parte de los compuestos necesarios. El cloruro de aluminio se utiliza en una cantidad de al menos 0,1 g/m^{3} de volumen de contacto, preferentemente en una cantidad de 1 a 10 g/m^{3}. El limite superior está determinado por la presión de vapor de saturación. La temperatura de los compuestos de cloruro de aluminio oscila entre la temperatura de sublimación de 170ºC y hasta 600 K por encima de la temperatura de transformación del vidrio. La duración del contacto de los vidrios con compuestos de cloruro de aluminio de la fase gaseosa oscila entre al menos 0,1 segundos en caso de altas temperaturas y hasta una hora en caso de bajas temperaturas. El limite inferior de la temperatura de la muestra de la superficie de vidrio está determinado por la resistencia del vidrio al cambio de temperaturas. El limite superior puede estar hasta 600 K por encima de la temperatura de transformación del vidrio. Al trabajar con cloruros de aluminio en la fase gaseosa se pueden lixiviar fácilmente posibles residuos débiles. Al emplear cloruro de aluminio se ha de diferenciar entre el uso con agua de cristalización y sin agua de cristalización. Con agua de cristalización se produce una modificación superficial más intensa y un aumento de la resistencia hidrolítica y de la microdureza de los vidrios, sin perjuicio óptico. Cuando se utiliza cloruro de aluminio anhidro se observan más fácilmente perjuicios ópticos perceptibles.Optical damage can be avoided if the aluminum material of the gas phase condenses on the surface of glass and at the same time becomes part of the compounds necessary. Aluminum chloride is used in an amount of al minus 0.1 g / m3 of contact volume, preferably in a amount from 1 to 10 g / m 3. The upper limit is determined by saturation vapor pressure. The temperature of the Aluminum chloride compounds range from the temperature of sublimation of 170ºC and up to 600 K above the temperature of glass transformation The duration of the contact of the glasses with gaseous phase aluminum chloride compounds oscillates between at least 0.1 seconds in case of high temperatures and up to one hour in case of low temperatures. The lower limit of the sample temperature of the glass surface is determined by the resistance of the glass to changing temperatures. The upper limit can be up to 600 K above the glass transformation temperature. When working with chlorides Aluminum in the gas phase can be easily leached Possible weak waste. When using aluminum chloride, differentiate between use with water of crystallization and without water of crystallization. With crystallization water a more intense surface modification and increased resistance glass hydrolytic and microhardness, without prejudice optical. When anhydrous aluminum chloride is used, they are observed more easily noticeable optical damage.
El procedimiento según la invención también se puede emplear ventajosamente en la producción de vidrio para tubos. En la producción de vidrio para tubos, como medio de soplado con sobrepresión en el proceso de Vello o el proceso de Danner se conduce aire a las superficies interiores de los tubos de vidrio. Se puede utilizar aire calentado a más de 170ºC que contiene AlCl_{3} evaporado. De este modo en primer lugar se evita una condensación. Este gas entra entonces en contacto en forma de capas de cebolla con la superficie interior caliente del vidrio, pudiendo tener lugar entonces la modificación de la superficie de vidrio. El gas sale después por la abertura del tubo en el extremo frió del tubo continuo, por lo que dispone de un tiempo de hasta varios minutos y de altas temperaturas (hasta 600 K por encima de Tg) hasta el corte del vidrio para reaccionar con la superficie del vidrio. En este contexto, para evitar la condensación puede ser necesario mantener la temperatura de corte del tubo por encima de 170ºC.The process according to the invention is also It can be used advantageously in the production of glass for tubes. In the production of glass for tubes, as a means of blowing with overpressure in the Vello process or the Danner process is conducts air to the inner surfaces of the glass tubes. Be you can use heated air at more than 170 ° C containing AlCl 3 evaporated. In this way, condensation is avoided first. This gas then comes into contact in the form of onion layers with the hot inner surface of the glass, being able to take place Then the modification of the glass surface. Gas comes out then through the opening of the tube at the cold end of the tube continuous, so you have a time of up to several minutes and from high temperatures (up to 600 K above Tg) until cutting of the glass to react with the surface of the glass. In this context, to avoid condensation it may be necessary to maintain the cutting temperature of the tube above 170 ° C.

Las cantidades de cloruro de aluminio introducidas en el recipiente correspondían a una superficie de vidrio de 3814 mm y un volumen de 20 m., debiendo pasar el cloruro de aluminio anhidro a la fase gaseosa a 180ºC, o de acuerdo con algunas mediciones DTA el material con agua de cristalización no se descompone hasta alcanzar temperaturas de 203ºC. Los recipientes se colocaron encima del material de muestra y después de 15 minutos de tratamiento en el horno de mufla se enfriaron con el mismo. La tabla 1 muestra diferentes pasos de tratamiento y su efecto en la resistencia hidrolítica.Figure 1 shows typical results of the Hydrolytic resistance of white silicate glass bottles of sodium and lime with the following composition: 71.0% SiO2, 1.7% Al 2 O 3, 0.02% Fe 2 O 3, 1.3% K 2 O, 15.5% Na 2 O, 9.4% CaO, 2.7% MgO and 0.25 SO 3, having been heated samples in an oven at temperatures of 550ºC with different amounts of AlCl 3 * 6 H 2 O and then cooled therein place. The amounts of aluminum chloride introduced into the vessel corresponded to a glass surface of 3814 mm and a volume of 20 m., the anhydrous aluminum chloride must pass to the gas phase at 180 ° C, or according to some DTA measurements the material with water of crystallization does not decompose until it reaches temperatures of 203 ° C. The containers were placed on top of the sample material and after 15 minutes of treatment in the Muffle furnace cooled with it. Table 1 shows different treatment steps and their effect on resistance hydrolytic

La figura 3 muestra estabilidad térmica de las capas y también los pasos de tratamiento. Una vez acabado el tratamiento, los vidrios fríos se sometieron a un tratamiento con llama. Se comprobó que la clara mejora de las resistencias hidrolíticas se mantenía de forma reproducible.Figure 3 shows thermal stability of the layers and also the treatment steps. Once the treatment, the cold glasses underwent a treatment with call. It was found that the clear improvement of the resistance Hydrolytic was kept reproducible.
En un horno de mufla se introdujo una cantidad definida (0,05 g y 0,15 g) de AlCl_{3} junto con una muestra de vidrio de plomo de 25 cm^{2} en un crisol de corindón, que se cubrió con lámina de aluminio. Después de un calentamiento a 470ºC y un tiempo de mantenimiento de 15 minutos, con desconexión final del horno de mufla y enfriamiento de las muestras en el crisol, se analizó la microdureza de los vidrios. Los resultados están representados en la figura 4 y muestran un aumento de más de un 100% de la microdureza después de una profundidad de penetración de 150 nm, y dicha microdureza puede adoptar valores incluso mucho mayores en caso de profundidades de penetración menores.A quantity was introduced in a muffle oven defined (0.05 g and 0.15 g) of AlCl 3 together with a sample of 25 cm2 lead glass in a corundum crucible, which is covered with aluminum foil. After heating at 470 ° C and a maintenance time of 15 minutes, with final disconnection of the muffle furnace and cooling the samples in the crucible, it analyzed the microhardness of the glasses. The results are represented in figure 4 and show an increase of more than 100% of the microhardness after a penetration depth of 150 nm, and said microhardness can adopt even much higher values in case of lower penetration depths.
